' The Schedule referred to in these Lettere Patent and making part of the same.

Be it known that I, OZI M. PIKE, of Leverett, in the county of Franklin, and State of Massachusetts, have invented a new and useful Machine for Cutting Vitreous and other like Substances; and I do hereby declare that the following isa full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this Speciiication, in which- A'represents the frame-work, which may be of any design or shape.

B B, friction-Wheels.

G, the cutter, consisting of a round piece'of hardeued steel, turning, near one end, onthe iiietion-Wheels, and at the other end in a socket in a thumb-screw, also of hardened steel. The object of the thumb-screw, friction-*Wheels and the steel socket is to make the friction ou the cutter, when in use, as little as possible.

D D are guards, to prevent the cutter from slipping or falling out of its place.

Ii' the cutter becomes dull, it may be sharpenedby a common hone or Whetstone, passed across the end, at right angles to the longitudinal diameter of the cutter.

The thumb-screw may be used to adjust the position ofthe cutter.

To cut vitreous or other like substances, place the point E of the cutter O on the surface to be cut, and draw the side of the frame along the straight edge 'or pattern, pressing uponl it at the same time. A fine line or scratch will be made in the glass, similar to that made by a diamond. f

What Iolairn as Illy-invention, and desire to secure by Letters Patent, is

A tool forcutting glass or other vitreous substance, constructed' to operate substantially as described.
